Arnold Drive Bridge
The Arnold Drive Bridge (also called the Jim Berkland Memorial Bridge and the Sonoma Creek Bridge) is a historic truss bridge in Eldridge, California in the United States. The bridge was built in 1930 over Sonoma Creek. The bridge serves as a connecting point between Eldridge and the village of Glen Ellen. In 1998, the bridge was named a historic bridge by the Sonoma League for Historic Preservation and was named a historic landmark by the County of Sonoma. History The Arnold Drive Bridge was built in 1930 over Sonoma Creek to replace a collapsed bridge made of concrete. The bridge is maintained by the County of Sonoma. On average, 13,900 cars travel over the bridge daily. The bridge had fallen into disrepair by 2000 and the County of Sonoma planned to tear the bridge down and replace it with a concrete bridge. Glen Ellen resident Jim Berkland, who used to play on and around the bridge as a child in the 1940s, collected signatures and filed a petition to the county, who ag ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Jim Berkland
James O. Berkland (July 31, 1930 – July 22, 2016) was an American geologist who controversially claimed to be able to predict earthquakes, including the 1989 Loma Prieta earthquake and 1994 Northridge Earthquake and who popularized the idea that some people are earthquake sensitive. He was profiled in a popular 2006 book as ''The Man Who Predicts Earthquakes''. The book includes a chapter that notes "Many of Berkland's theories--based on tides, moons, disoriented pets, lost cats and dogs, and magnetic field changes--were factors in the great Indian Ocean quake-tsunami disaster on December 26, 2004." but neither his methods nor his predictions have been published in any scientific journals for peer review. His results have been disputed by peers, with other scientists going so far as calling him a crank and a clown. Career Jim Berkland studied geology at the University of California, Berkeley earning the Bachelor of Arts degree in 1958. Thereafter he worked for the United States ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
October 2021 California Rainstorm - Sonoma - 2021-10-24 - Sarah Stierch 05
October is the tenth month of the year in the Julian and Gregorian calendars and the sixth of seven months to have a length of 31 days. The eighth month in the old calendar of Romulus , October retained its name (from Latin and Greek ''ôctō'' meaning "eight") after January and February were inserted into the calendar that had originally been created by the Romans. In Ancient Rome, one of three Mundus patet would take place on October 5, Meditrinalia October 11, Augustalia on October 12, October Horse on October 15, and Armilustrium on October 19. These dates do not correspond to the modern Gregorian calendar. Among the Anglo-Saxons, it was known as Winterfylleth (Ƿinterfylleþ), because at this full moon, winter was supposed to begin. October is commonly associated with the season of spring in parts of the Southern Hemisphere, and autumn in parts of the Northern Hemisphere, where it is the seasonal equivalent to April in the Southern Hemisphere and vice versa. ...
